Effective January 1, 2016, the State of Delaware Office of Animal Welfare assumed animal control duties from the counties. This includes dog licensing.
Dog licensing purchases and renewals are available by calling 1-877-730-6347 or visiting Petdata.com.
Renewal notices are expected to be mailed out by the end of January. If your license expires before then, you will be automatically granted a temporary extension until you are able to purchase a state license and, therefore, no further action is needed on your part at this time.
